The discussion is about shore power options for a 1982 Nonsuch 26 boat without a shore power inlet. Siva Surendira is considering using a pigtail adapter to run a heater and charge batteries, but jonlewit and others have raised concerns about safety and the limitations of the pigtail adapter.
jonlewit points out that the Marinco pigtail adapter has 12-gauge conductors, which are inadequate for 30 amps, and the triple female connector is only rated for 15 amps. Brian M. Godfrey suggests using a single plug pigtail with a GFCI adapter and a SmartPlug cable with tinned conductors for better safety.
Several users, including Joe Valinoti, Brian Godfrey, and SVHippo, emphasize the importance of installing a proper shore power connection, such as a SmartPlug or a North American industry-standard connection, with a galvanic isolator or isolation transformer, and an AC panel with an ELCI and reverse polarity disconnect.
Mark Powers provides a step-by-step guide on how to safely connect and disconnect shore power, and Bob warns about the risks of fires and electrical accidents, advising users to inspect their cords and sockets regularly and to use corrosion-blockers.
Overall, the discussion highlights the need for careful consideration of safety and electrical system requirements when installing shore power on a boat.
